Drug Wars and Criminal Violence in Mexico


For the last several years, I have been working on a project with two Mexican co-authors Sandra Ley and Guillermo Trejo on criminal violence in Mexico. Mexico is currently in the midst of drug wars that have killed over 250,000 people since 2006. More than 50,000 have disappeared. The project began with a simple question: why do native American municipalities in Mexico have lower homicide rates compared to non-native American municipalities? Mexico today is about 12% Native American.  Our work examines a region in Mexico where native peoples have deterred narco-traffickers from taking over their land and resources: the mountain and coastal region of eastern Guerrero state, which is about 4 hours south of Mexico City.

Eastern Guerrero is majority Native American, poor, rich in material resources, and a desirable place for drug traffickers to cultivate marijuana and poppy, which is the base ingredient in heroin. In the mid-1990s, native communities in this region created their own parallel legal system and community police force. They found that they couldn’t rely on Mexican state authorities to execute justice and ensure their safety. Community authorities are monitored and controlled by town assemblies, which keep them accountable to the people they serve. Regional legal tribunals hear cases and issue sentences. Community police coordinate on the regional level by sharing information and defending external boundaries. We found that this system of regional justice and policing lowers homicide rates. It has also kept communities socially unified. We hope that policymakers in Mexico and others are persuaded by our work to legally protect community-based institutions like those of eastern Guerrero.
